Abstract
Abstract: The work on simulation of mixing of planar jets in a room has been continued. Earlier large eddy simulations did not produce adequate results, because one jet eventually pushed the other jet away. In this work velocity fluctuations have been applied to the inflow. Most of the simulation work is about testing turbulence models and discretization schemes of the momentum equation. The open source finite-volume code OpenFOAM-1.5 has been used in the simulations. Main result: The simulation results are improved, but the flow could not be predicted accurately enough. Modelling strategy still needs reconsideration.Description
